This page provides access to greenhouse gas (GHG) data for
Annex I Parties in a "map" format which complements the same data presented elsewhere on the UNFCCC
data interface in tabular and graphical formats. Information is provided on anthropogenic emissions by
sources and removals by sinks of the six principal GHGs for the period from the base year to the latest
available year, which is usually 2 years before the current year. GHG inventories are developed by Parties to
the Convention using comparable methodologies agreed upon by the Conference of Parties. At present, all Annex
I Parties base their GHG inventories on the Intergovernmental Panel on Climate Change (IPCC) Revised
Guidelines for National Greenhouse Gas Inventories (1996), IPCC Good Practice Guidance and Uncertainty
Management in National Greenhouse Gas Inventories (2000) and IPCC Good Practice Guidance on Land Use,
Land-use Change and Forestry (2003).

Only key GHG data, such as national totals and emissions/removals for the major sectors/sub-sectors, are
provided in this part of the GHG data interface. For more detailed information, other parts of the interface
should be used, such as "Detailed data by Party" or "Flexible queries".

By default, the map shows changes in total aggregate GHG emissions (including emissions/removals from the
LULUCF sector) between the base year defined under the Climate Change Convention and the latest available
year. To display other data, the user should select options from the three dropdown lists, as shown below. In
essence, a combination of sector/subsector, gas and year has to be selected. Depending on the selections
made, the appearance of the map and the list below it are automatically updated.

The map is interactive so that with the use of the scroll bars, one can move the view of the map up, down, to
the right or to the left, and also zoom it in or out. There are markers attached to countries; when the
cursor is placed on a marker, information on total GHG emissions for that country is displayed. Note that
such markets become visible only when the resolution of the map is sufficient; for example, to see markers
for relatively small countries one has to zoom in the map sufficiently.

The list underneath the map is by default sorted by value in ascending order. To change the sorting order
(such as sorting by Party name), click on one of the sorting options (see the screenshot below). The Party
names on the list, as well as the tags on the map, link to the emission details for that Party, which
includes: (1) a summary table by sector and (2) a graphical representation of the contribution of each sector
to the national total including LULUCF.

The 'Full report' is a hyperlink to the GHG profile (in PDF) for that Party.

The definitions of the different fields used in the map are as follows:

Sector or sub-sector: GHG emissions/removals estimates are
presented in accordance with the categories (sectors, sub-sectors or even more detailed categories) as
defined in the IPCC Guidelines for National GHG Inventories (1996) which cover most activities emitting
or removing GHGs. A complete list of the sectors and their definitions is provided in Chapter 1 of the
Volume 1 (Reporting Instructions) of the Revised 1996 IPCC Guidelines for National GHG Inventories. It
can be accessed on the IPCC website at
http://www.ipcc-nggip.iges.or.jp/public/gl/guidelin/ch1ri.pdf. For methodological reasons, although
GHG emissions from international bunkers (aviation and marine) are included in the list of the sectors,
those emissions are excluded from national totals.

In addition to the sectors and/or sub-sectors, GHG emissions/removals data are also presented for total
GHG emissions or “totals”. There are two kinds of totals: total emissions including LULUCF or
“net total emissions”, and total emissions excluding LULUCF or “gross total
emissions”. LULUCF stands for Land Use, Land-use Change and Forestry, and is the only sector that
may emit into or remove GHGs from the atmosphere depending on whether the sector or sub-sector is a
source or a sink.

Gas: In estimating the national anthropogenic GHG emissions by
sources and removals by sinks, the six principal gases that are not controlled by the Montreal Protocol
are taken into account. These six gases are carbon dioxide (CO2), methane (CH4),
nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur
hexafluoride (SF6). The term "aggregate GHGs" refers to a sum of these six gases;
the sum is taken using the so-called Global Warming Potentials (GWPs) of each gas. The use of GWPs
converts emissions/removals of various GHGs into the so-called CO2 equivalent.

Inventory Year: There are two years that are relevant for the GHG
inventories submitted by the Parties: submission year and inventory year. Submission year refers to the
year in which the GHG inventory is submitted to the UNFCCC secretariat while inventory year refers to the
year for which the GHG emissions/removals data are estimated. Under the process of the Climate Change
Convention and the Kyoto Protocol, the inventory year lags the submission year by 2 years, e.g., in 2008,
Parties submitted GHG inventories with 2006 as the latest available year. In addition to the emissions
time series from 1990 to the latest available year, the users also have the option to select a series
with changes from the base year to the latest available year, and a change over the period 1990 to the
latest available year. The base year for Annex I Parties under the Climate Change Convention is normally
1990 but some Parties are allowed to use a base year other than 1990. These Parties and their base years
are Bulgaria (1988), Hungary (average of 1985-1987), Poland (1988), Romania (1989) and Slovenia (1986).

Color legend: The color legend bar shows the relationship
between the colors in the map and the values. The color gradients ranging from light purple to blue
indicate absolute emissions (if emissions data are displayed on the map) or positive growth (if a trend
is displayed); those ranging from light to dark green indicate carbon sinks (for emissions/removals data)
or negative growth (for trend data); and yellow nuances indicate growth rates close to 0%. For the LULUCF
sector, the gradients of green show removals, while the gradients of purple show emissions.

The scale of the bar dynamic and is dependent on the range of values for a particular category/year
selection.

European Union: European Union (27) refers to the 27 member States
of the European Union and is a Party to the Convention. European Union (15) is a Party to the Kyoto
Protocol and refers to the 15 member States prior to May 2004 (Austria, Belgium, Denmark, Finland, France,
Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden and United Kingdom of
Great Britain and Nothern Ireland).
